Bit of a downer given how far we've taken the design and that I'd come up with a natty little solution that stood to make savings against budget of several million pounds (which my company would get a decent cut of).

Needless to say the mood in the office as we pack away files and archive data is not the best.

On the plus side though, I no longer care as to why the Mechanical Engineers spent 5 months saying we need two 'X's and then last week suddenly decided they really wanted three. I mean it's only a case of whole rafts of the design having been based around their original answer...not a problem to suddenly change your mind at the eleventh hour, oh no...

Obviously this issue is now something of a moot point and the fact that I don't now need to get to the bottom of it all and bang heads together is a little bit of silver lining at least.
